Title: Image reader and imaging device
Inventor: MIYAJIMA MASAMI
IPC: H04N1/04
Filed: 2001-02-09
Abstract: PROBLEM TO BE SOLVED: To minimize deterioration in the image data quality and extension of the reading time of the image data caused by an intermittent reading operation. SOLUTION: When the capacity of a transfer memory of read output image data becomes full, scanning of a traveling body with a read section placed thereon is stopped, and read data are not outputted. No intermittent reading is conducted during a motor through-up/through-down operation and data are read only in a constant speed operation, so as to avoid the problem of interleaving. Thus, the traveling body is returned from a stop position, and data are read at a constant speed from a read interrupted position, in the case of re- reading the data.  The reading time can be reduced, as shown in Figure 10 (B), by adopting a pattern for returning capable of a higher speed operation as a speed control pattern in the through-up/through-down operation in the case of returning, without having to employ conventional methods, as shown in Figure 10 (A), where the same speed control pattern is used between the read pattern and the returning pattern.
